Hi Marmuta, What do I do, I have two ethernet ports, one (eth0) not used, the other (eth1) being used
~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:07:95:44:10:db UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:18 Base address:0xc800 eth1 Link encap:Ethernet HWaddr 00:08:a1:92:56:33 inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::208:a1ff:fe92:5633/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:6801947 errors:0 dropped:0 overruns:0 frame:0 TX packets:7413867 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4229253367 (4.2 GB) TX bytes:2328395793 (2.3 GB) Interrupt:22 Base address:0xcc00 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:5403 errors:0 dropped:0 overruns:0 frame:0 TX packets:5403 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1102931 (1.1 MB) TX bytes:1102931 (1.1 MB) Can you tell how should I give my tcpdump? Using the above I get this :- $ sudo tcpdump -nls128 host 192.168.1.1 | tee tcpdump.txt [sudo] password for shirish: tcpdump: WARNING: eth0: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 128 bytes ^C0 packets captured 0 packets received by filter 0 packets dropped by kernel This is though on Intrepid atm but still would love to know how. -- Regards, Shirish Agarwal This email is licensed under http://creativecommons.org/licenses/by-nc/3.0/ http://flossexperiences.wordpress.com 065C 6D79 A68C E7EA 52B3 8D70 950D 53FB 729A 8B17 -- IPV6 causes slow internet access https://bugs.launchpad.net/bugs/313218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
